Easy Expedia Interview Questions: Strategy Guide

Easy questions at Expedia are designed to assess fundamental programming competency, logical thinking, and clean code habits. They form the baseline of their technical screening, often appearing in initial phone screens or as the first part of a multi-problem interview. While conceptually simple, they require precise implementation and an understanding of core data structures like arrays, strings, and hash maps. Success here is non-negotiable; failing an easy question typically ends the interview process.

Common Patterns

Expedia's easy problems frequently test a few key areas. String and array manipulation is paramount, often involving tasks like validation, transformation, or searching. Another common pattern is basic hash table usage for counting or lookups to achieve O(n) time complexity. Simple two-pointer techniques also appear for tasks like checking palindromes or merging sorted data.

# Example: Two Sum (Hash Map pattern)
def two_sum(nums, target):
    seen = {}
    for i, num in enumerate(nums):
        complement = target - num
        if complement in seen:
            return [seen[complement], i]
        seen[num] = i
    return []

# Example: Valid Palindrome (Two-pointer pattern)
def is_palindrome(s):
    left, right = 0, len(s) - 1
    while left < right:
        if s[left] != s[right]:
            return False
        left += 1
        right -= 1
    return True

Time Targets

You should aim to solve an easy Expedia question within 10-15 minutes total. This includes the time to understand the problem, discuss your approach with the interviewer, write clean code, and walk through test cases. The first 2-3 minutes should be for clarifying questions and outlining your logic. The next 5-7 minutes are for coding. Reserve the final 3-5 minutes for testing edge cases and discussing complexity. Being methodical but efficient is key; rushing can lead to overlooked bugs, while being too slow suggests a lack of fluency.

Practice Strategy

Do not just solve these problems. Practice them under strict time constraints to build speed and confidence. For each problem, first identify the core pattern. Write the code by hand or in a plain text editor to simulate a whiteboard environment. After solving, immediately analyze your solution's time and space complexity aloud, as you would in an interview. Finally, rehearse explaining your reasoning clearly and concisely. Focus on writing idiomatic, readable code with meaningful variable names—Expedia values maintainability. Their easy questions are a filter for sloppy coders; your practice should aim for flawless execution.
